Product Details

High-strength raise boring drill rods with long service ability and durability

 

Our high-strength raise boring drill rods are designed and manufactured with an emphasis on durability, weight reduction, and long service ability. Our drill rods are designed to be compatible with all of the raise drills operating.

The threaded connections on the rods are cut to exacting standards and verified by our standard inspection.

The rods are also designed with patent technology that contribute to long life and service ability. With proper care and maintenance, the threaded connections are designed to provide years of trouble-free service.

 

Raiseboring steel

The steel used in the production of our drill rods is vitally important because rods must be able to withstand tremendous loads. Understanding that not all steels of a specific grade are produced to the same quality level and knowing the catastrophic effects of a drill string failure, we are committed to providing value to you through high-quality products demonstrating durability and strength.

 

Two grades of steel available

Products are offered in two distinct grades of steel, according to the size of the drill and the size of the shaft. We normally use DRB40 and 4330V rod steel materials for raise boring drill rods.
